A moving body position detection system including an unit acquiring dead reckoning navigation information including a moving body direction; a unit identifying a moving body position based on the dead reckoning navigation information on the moving body; a unit predicting a predicted arrived position of the moving body after a predetermined interval from the position of the moving body based on the dead reckoning navigation information on the moving body; a unit calculating a difference direction angle between a direction from the position of the moving body to the predicted position and the direction of the moving body; a unit correcting the difference direction angle if it is equal to or larger than a threshold; and a unit updating the moving body position based on the difference direction angle.

Moving body position detection system, moving body position detection apparatus, moving body position detection method, and computer-readable storage medium

A moving body position detection system including a unit that acquires dead reckoning navigation information on a moving body; a unit that identifies a position on the moving body on a link based on the dead reckoning navigation information on the moving body; a unit that acquires current position link data on a current position link and neighboring link data on a neighboring link. The current position link is a link on which the moving body position is located, and the neighboring link is connected to the current position link. The system also includes a unit that compares the dead reckoning navigation information on the moving body with the current position link data and with the neighboring link data; and a unit that updates the position of the moving body based on a comparison result of the comparison unit.
